Product Description

About products

Chromium plated rod refers to a layer of chromium with a hardness of 50-60 formed by electroplating on the surface of a hard optical shaft, which is suitable for matching use in the automation industry and linear bearings. The surface of a chrome plated rod looks like a rod product, but its application range is still very wide. In addition, there is a layer of chrome plated layer on its surface, which has characteristics such as abrasion resistance, corrosion resistance, heat resistance, etc. It can also increase the hardness and finish of the surface
